The following is changed in this commit: - The constructor for NewtonIterationBlackoilSimple now takes a parameter object instead of a linear solver. - The fully implicit black-oil simulators can now use the CPR preconditioning strategy (by passing use_cpr=true) or the simple strategy (the default). Note that as of this commit, the CPR preconditioning still has not been implemented properly, and behaves just like the simple strategy.
